Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance are essential. Lexus recommends performing the follow-
ing maintenance:
Scheduled maintenance
Scheduled maintenance should be performed at specified
intervals according to the maintenance schedule.
For details about maintenance items and schedules, refer to the
“Lexus Service Booklet” or “Lexus Warranty Booklet”.
Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have
a little mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools
and skills. These are best performed by qualified technicians. Even
if you’re an experienced do-it-yourself mechanic, we recommend
that repairs and maintenance be conducted by any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional. Any authorized Lexus dealer or repairer will keep a
record of maintenance, which could be useful should you ever
require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Lexus repairer
to service or maintain your vehicle, we recommend that you

CT200h_EE (OM76041E)
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air
conditioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (P. 494)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also, a backfire could cause a fire in the engine com-
partment.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
